What dedicated freight means
Dedicated freight means a truck and driver assigned to one shipper's freight instead of a shared network. The term covers two arrangements. Dedicated contract carriage assigns a fleet and drivers to one company for months at a time, usually on fixed routes. A dedicated, exclusive-use truck carries only your load on a given run, from pickup straight to delivery.
Both share the same core idea. Nothing else rides with your freight, the truck takes a direct route, and you get more control over timing than a shared network allows.
